I want to put a packman game on my *.xhtml page.(I am using jsf 2 and primefaces 3.5)

However,

when I "translated" the html page in xhtml I get an error at this script:

 <script> var el = document.getElementById("pacman"); if (Modernizr.canvas && Modernizr.localstorage && Modernizr.audio && (Modernizr.audio.ogg || Modernizr.audio.mp3)) { window.setTimeout(function () { PACMAN.init(el, "./"); }, 0); } else { el.innerHTML = "Sorry, needs a decent browser<br /><small>" + "(firefox 3.6+, Chrome 4+, Opera 10+ and Safari 4+)</small>"; } </script>

if (Modernizr.canvas && Modernizr.localstorage && 

i get:

The entity name must immediately follow the '&' in the entity reference.

Any idea how to fix that?
